Nationally notorious political operative Roger Stone, a friend and ally of Broward Sheriff Scott Israel, has been banned from appearing on CNN.

The blog Media Matters for America reported CNN's decision on Tuesday, and applauded it. The news network said it decided not to air Stone anymore after viewing some of his tweets disparaging minorities who appeared on their political programs.

Some of Stone's tweets, from his account @RogerJStoneJr:

• Tweeting about CNN commentator Ana Navarro last week, he wrote (Note: We've censored the profanity with hyphens): "Why do all the make-up people and hair-stylists at CNN New York HATE @anaNavarro ? Entitled Diva B----" Then he responded to a tweet saying, "no , she's a MORON. Borderline retarded." On Tuesday, he wrote in a tweet that Navarro is a "pompous sh—head'' and in another, he said she was going to kill herself.

• In November 2012, Stone tweeted about black CNN commentator Roland Martin: "Who is this stupid negro Roland Martin ? Buffoon or token Buffoon ? #CNN" Martin responded: "stupid Negro"? I'm the reason guys like you didn't want Black folks to learn to read. I'm glad to tick you off any day.'' In a tweet this week, Stone told the most recent critic of that 2012 tweet to "Kiss my a--"

The sheriff's relationship with Roger Stone is a bond of contradictions,...

A campaign operative who built his career on smearing political enemies, publicly calls women the C-word and consulted for attorney-turned-Ponzi-schemer Scott Rothstein has become one of Sheriff Scott Israel's trusted political guides.

They were not the first tweets from Stone that drew offense. A search on Stone's Twitter account for a variety of offensive terms turns up all manner of insults he's hurled over the years regarding women, fat people, black people who eat fried chicken, minorities he thinks were hired just to meet quotas, and more. In a December tweet, he said it's "not over until its over. Hillary better watch her fat a--.''

Stone, a Fort Lauderdale resident, openly relishes his role in gutter politics, eschewing diplomacy. His lack of political correctness and willingness to engage in political skulduggery have made him famous. Nearly all references to him in print remind readers that he's a "dirty trickster'' who's been involved in politics since working to get President Richard Nixon elected.

Among his in-your-face tactics was once creating an anti-Hillary Clinton PAC with the name "Citizens United Not Timid,'' for the vulgar acronym.

His pro-Sheriff-Israel Twitter account, the "Broward Bugle," tweeted a few years ago to a Sun Sentinel editor "C U Next Tuesday,'' which has the same crude acronym.

Israel used Stone's attack dog campaign prowess to win election in 2012, and did not denounce his tactics. Israel didn't respond to a text message and email Thursday asking if he's using Stone in his 2016 re-election campaign, and whether he has a comment on Stone's latest controversy.

But Stone pal Ron Gunzburger, general counsel for the Broward Sheriff's Office and the person who introduced the sheriff to Stone, said he'd welcome the help.

"Roger is a friend and I would always welcome his campaign advice,'' Gunzburger said. "He's a smart guy, even though our politics are rather sharply different.''

Stone, who lives in Fort Lauderdale's Coral Ridge community with his wife and pets, said in an email that he has "bigger fish to fry in 2016,'' when it comes to election assistance.

"I have never planned or expected to play any formal role in the Sheriff's re-election campaign,'' he wrote. "I will certainly vote for the Sheriff. He's doing a great job and I am proud to call him a friend.''

Stone was working on Donald Trump's presidential bid — their relationship dates back decades — until Stone said he quit and Trump said he fired him.

Stone still is supporting Trump, and did so during his most recent appearance on CNN on Sunday.

Stone says the real reason CNN disowned him is that he's been battering the Clintons, which he said also got under the skin of David Brock at the nonprofit Media Matters for America (mediamatters.org).

"My exposing Bill Clinton's serial rapes and Hillary's bullying his victims seems to have gotten under @davidbrockdc's skin -@ClintonsWar,'' Stone wrote in a recent tweet.

Among the books Stone wrote and is busy selling is one about Hillary Clinton, the Democratic presidential candidate, entitled "The Clinton's War on Women."

Stone doesn't usually get involved in local races, but he did in 2008 and 2012 when the sheriff's post in Broward was hotly contested.

In 2008, when Stone was working with lawyer Scott Rothstein before he was exposed and imprisoned as a Ponzi schemer, Stone worked to keep then-Sheriff Al Lamberti in office. Lamberti's opponent that year was Democrat Scott Israel, whom Stone attacked.

But after reading a comment in the newspaper from the victorious Lamberti, downplaying Stone's role in the win, Stone switched sides. In 2012, Stone helped Israel unseat Republican Lamberti.

Israel then hired three of Stone's closest associates, and transferred his stepson to a detective position at the agency.
